SPECIFICATION forming part of Letters Patent No. 400,445, dated April 2,1889.

Application filed May 12, 1888.

To all whom t may concern:

fBe it known that I, OTIs E. DAVIDSON, of Nashville, in the county ofDavidson and State of Tennessee, have invented certain new and usefulImprovements in Seal-Locks; and

`I do hereby declare the following to be afull,

' production of an improved car-door seal and lock not easily broken ordestroyedY by the rough usage to which they are subjected. To this endthe invention consists in certain novel details of construction andcombinations and arrangements of parts, to be hereinafter described, andpointed out particularly in the claims at the end of this specification.

In the accompanying,r drawings, Figure 1 is a front elevation of a sealand lock constructed in accordance with my invention. Fig. 2 is asectional view on the line 0c Fig. 1. Fig. 3 is an elevation lookingfrom the bottom. Fig. 4 is a similar View looking at the side away fromthe hasp. Fig. 5 is a view of the rear side.

Similar letters of reference in the several figures indicate the sameparts.

The base A of the device is preferably castiron, having a recess, B, inthe under side and the extensions C at top and bottom, in which areholes for the insert-ionof bolts to hold the device in position on thedoor-j amb. The central portion, D, on the outside is raised slightlyabove the general surface and has an on the spindle portion to affordthe necessary room for the hasp between the shoulders H and the base D.On one of the shoulders H is located a slight projection, with alargelheaded stud, K, thereon, corresponding to the Serial No. 273,678.(No model.)

head F on the stud e. The end of the turnbolt G- projects through thebase A and into the recess B in the under side, and has rigidly securedthereon a ratchet-wheel, M, with vwhich a pawl, N, on the base engages,being held in engagement by the long spring O, all said parts beinglocated Within the recess before mentioned.

The parts having been assembled as above described, when it is desiredto lock and seal the door, the door is closed and the hasp placedoverthe turn-bolt and beneath the two shoulders H, the bolt being thenturned until the studs F and K are near each other, when a seal, L,having a slot therein, a portion of which at a point intermediate theends is widened to permit the heads to pass through, is slipped oversaid heads and the bolt further rotated until the studs are drawn to theends of the slot, when it will be found that the seal cannot be removedwithout being broken, as the turn-bolt cannot be turned backward byreason of the ratchet and pawl on the under side, as will be readilyunderstood. The seal above mentioned has an extended section to one sideof the slot, on which is placed the directions as to the destination ofthe car, &c., which, it will be seen from Fig. 1, are exposed inconvenient position for reading. As an additional security, a padlockmay be passed through the ring g, although when the seal is made ofsheet metal it alone will be found to be sufiicient to resist theturning of the bolt, the two shoulders H on the latter bridging the slotin the hasp and taking up all strain on the hasp itself.

I do not wish to be limited to the exact mechanism herein described, asit is obvious` studs on the turn-bolt and base, respectively,
